MACHINE FOR ASSEMBLING SOLE-LEATHER AN D MATS.

Application filed June 4, 1917, Serial No. 172,889.

To all whom it may concern:

Be it known that I, ARTHUR O. HAYDEN, States, and resident of Brockton, county of Plymouth, Commonwealth of Massachusetts, have invented an Improvement in Machines for Assemblin Sole-Leather and Like Mats, of which the ollowing description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to machines for assembling died out pieces of material such as from sole leather and making the same up into mats for doorways, passages and the like. The principal objects of the invention are to provide an improved construction and arrangement of mechanism and operating parts wherebythe died out sole leather pieces constituting elements of link blocks for the mat, may be quickly and conveniently assembled and threaded on cross rods adapted to tie the built up link blocks of -the mat together into a unitary mat formation; also to 'rovide for the convenient and rapid hand ing of the died out sole leather elements to make them into link blocks for the mat of substantially uniform size, in the most expeditious manner. The foregoing and other objects and advantages of the invention will more fully appear from the following detailed description, and

the distinctive features of novelty will be pointed out in the appended claims.

- Referringv to the drawings;

venient elevation for the operator. At the sides of the topof the frame stout rods or bars 12, 12 are fixed, these being shown as supported by .lugs- 13 secured to the frame.

hese rods or bars 12 constitute guide rails on which the operating devices of the machine are slidably mounted. Toward the back of the machine a bar 14 extends transversely thereacross having at its ends bearing blocks 15 slidably fitted on the rails 12 and equipped with clamping nuts 16 for securlng said bar in adjusted position. The bar 14 is a composite formation composed of a lower portion 14" and an upper portion 14 adapted to fit thereon, the opposing faces of these two portions having corresponding notches, which constitute compleof holes 17 a-da ted to receive the inner portions of the ro s R on to which the link blocks of the mat are threaded, the holes 17 being small enough so that as the rods R are set into the notches of the lower bar portion 14, and the upper bar portion 14 is fitted down thereonto, said rods may be clamped securely to the bar by setting up clamp screws 18 which extend through the bar portions at spaced apart intervals and are equipped with thumb nuts 19 at their tops for convenient operation. The rods R as commonly employed are in U-form, z. e., the rods are formed in pairs with a connecting portion at their inner ends as seen at 1*. As the rods are 0- siti-oned as described in the composite a1 14,. the connecting portions 1" come against the rear side of the bar 14 and they are held thereagainst so that the rods are restrained from sliding movement with respect to the bar by a plate 20 which extends substantially the length of the plate 14 and 1s loosely held at the back thereof with a capability of swinging movement by a series of holding screws 21 which pass oosely through. holes of said plate and into the bar portion 14". .The extent of play thus permitted the plate 20 is sufficient so that the rear portions 14 of the rods may come to rest at the back of the bar, and the screws 21 may be adjusted so as to prevent any relative backward sliding of the rods in the assembling operation to be described. Slid- ,ably fitted to the rods 12 adjacent the front of the machine is a relatively wide plate 22,

the ends of this plate being supported by bracket pieces 23 which are guided on said rods. Mounted at each side of the top of the plate 22 are rails 24, 25 spaced apart a distance corresponding to the width of the link blocks to be built up from the died out leather pieces; the spacing of these rails as shown being suificient to accommodate four of the leather pieces P of the thickness shown. Slidably fitted on the plate 22 between the rails 24, 25 is a slide 26 extending the length of said plate and having projecting ends equipped with stop pieces 27, 28, spaced so as to permit a definite limited sliding movement of the slide 26 with respect to the plate 22. The slide 26 is provided with spaced apart dividing posts 29, these dividing the space between the rails 24, 25 into compartments of a length corresponding to the length of the link blocks as formed from the died out leather pieces. The rails 24, 25 are transversely slotted from their tops as seen at 30, 31 at intervals corresponding to the spacing of the holes 17, 2'. 6., according to the required spacing apart of the rods R in the formation of the mat. The depth of the slots 30, 31 is such that as the rods R rest in the bottoms thereof, they are in alinement with the holes H of the built-up link block, the several leather pieces of which are held in lengthwise and vertical alinement in the compartments determined by the rails 24, 25 and the division posts 29 as already explained. The stop pieces 27, '28 are so positioned that in one limit of movement of the slide 26, the set of rods will be in alinement with the holes H of the link blocks as assembled in the compartments of the slide 26, as required for the positioning of alternate rows of link blocks in assembling the mat, while when the slide 26 is moved to its other limiting pos1- tion, the assembled link blocks present other holes in alinement with the rods for assembling the intermediate rows of link blocks, that is, in use the slide 26 is first moved to one limiting position and one row of link blocks assembled. on the rods, then moved to its other limiting position and the next row of link blocks slipped on the rods, then back to its first position for the next row, and so on until the mat is completely made up. For accurately alining the entrance ends of the rods R into the holes of the link blocks to be assembled, a gage plate 32 may be adjustably clamped at the inner side of the rail 24 by means of clamp screws 33 passing through vertically elongated slots 34 of said plate. The rail 25 has pivoted to the front thereof at its opposite ends as seen at 35 a swinging plate 36 which normally rests in a lowered horizontal position. This plate is equipped with projecting handles 37 by which it may be swung upward to an inclined position, in which 'of the desired width.

position its inclined face intersects the line of the rods R as projected through the bottoms of the slots 30, 31. The plate 22 is adapted to be slid in operation along the rails 12 by an operating device consistmg in lever arms 38 secured at opposite sides of the frame to a shaft 39 and having their forward as far as permitted by the stop lugs 47.

In use, the plate 22, being in its normal forward position as held by the spring :45, the rods R are fitted in place with their respective ends in the holes 17 and in the slots 30. The died out pieces of leather are conveniently kept in a hopper 48 at the front of the machine and these are picked out by the operative and selected so as to fill the several compartments of the slide 26. Then the treadle is operated and the slide moved inward so that the rods are slipped through the holes H of the assembled link blocks. This being done, the operative swings up the plate 36 and further movement of the slide 22 will raise the rods R gradually upward by their engagement with the'inclined face of the plate 36, this lifting the assembled link pieces P out of their respective compartments on the slide 26, this lifting being continued until the link pieces P clear the top of the rail 24 when the assembled link pieces for the series of links to make up a line across the mat, may be allslid bodily along. the rods R up against the bar 14, or against the foremost line of already assembled {links after the mat is started, by first moving the slide 22 back far enough so as to engage the rail 24 behind the line of links to be pressed into assembled position. This operation is continued until the link blocks are all assembled on the rods R to complete a mat In making up mats of the described type, it is customary to fill in the spaces between alternate links at the ends of the mat with leather pieces .died

of the mat, these filling pieces being of a width to partially fill up the compartments in which they are placed leaving only room enough therein to receive and hold in alinement the round pieces P as shown in Fig. 4. I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope'of the invention.

Having described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. A machine of the kind described, comprising means for holding in spaced apart parallel relation a series of rods to receive assembled pieces making up link blocks of a mat, and a slide mounted for movement transversely of the rods thus held and equipped with spaced compartments adapted to gage the number of pieces required for each link block, the movement of said slide bringing said compartments into two different positions with respect to said rods whereby successive lines of links may be slipped on said rods in alternating relation.

2. A machine of the kind described, comprising means for holding in, spaced apart parallel relation a" series of rods to receive assembled pieces making up link blocks of a mat, a slide mounted for movement longitudinally of said rods, and a second slide superposed thereon mounted for limited movement transversely of said rods, said second slide equipped with a series of spaced compartments adapted to gage the number of pieces required for each link block, said slide having two limiting positions for slipping assembled links on to said rods in alter natlng llnes respectively.

2 3. A machine of the kind described, comprlsmg means for holding in spaced apart parallel relation a series of rods to receive assembled links on to said rods in alternating lines respectively, and means for lifting the ends of said rods with the link pieces fitted thereon out of said compartments upon a continued 'movement of the first named slide.

4. A machine of the kind described, comprising means for'holding a series of rods in parallel spaced relation, means for assembling pieces of relatively thin material into link blocks and presenting said blocks in position for assemblage on the rods so held, and means for freeing the link blocks so built up, from the last named means whereby they may be assembled on said rods.

5. A machine of the kind described, comprising means for holding in spaced apart parallel relation a series of rods to receive assembled pieces making up link blocks of a mat, a slide mounted for movement endwise of said rods, 2. second slide mounted on the first named slide for movement to either of two limiting positions transversely of said rods, said second slide equipped with a series of spaced compartments adapted to gage the number of pieces required for each link block, and having also provision for holding in definite spaced relation the ends of said rods, the two limiting positions of said slide presenting its compartments in position to slip links on to said rods in alter nating lines respectively, and a hopper for holding link pieces mounted directly in front of said slides.

In testimony whereof I have signed my name to this specification.

ARTHUR C. HAYDEN.
